【摘要】 采用在轴承外圈上安装套圈并粘贴应变片的方法对二级齿轮减速机箱体所受的动态激励力进行了测试和分析，并在此基础上得出了有关影响减速机箱体动态激励力的主要因素的有益结论。对减速机动态设计和减速机故障诊断有着积极的意义。更多还原

【Abstract】 in this paper, dynamic exciting forcesacting on the body of a two-stage helical gear unitare tested and analyzed by putting the ring ontoouter ring of bearings and sticking the strain-gaugeon the ring.The conclusions about the major fac-tors affecting dynamic exciting forces of a gear unitare derived from the test information, which are veryuseful for dynamic design and fault diagnosis of gearunits.更多还原
